In Beyond the Boomerang: From Transnational Advocacy Networks to Transcalar Advocacy in International Politics, editors Christopher L. Pallas and Elizabeth A. Bloodgood offer cutting-edge scholarship that synthesizes a new theoretical framework to develop a coherent, integrated picture of the current dynamics in global advocacy. This new theory of transcalar advocacy focuses on advocacy activities and policy impacts that transcend different levels or scales of political action. In transcalar advocacy, all NGOs–northern and southern–are treated as strategic actors, choosing the targets, scales of advocacy, and partnerships that best suit their capacities and goals. The case studies in the volume develop the empirical grounding of this theory using data from Latin America, Africa, Europe, and Asia, with several chapters featuring cross-national comparison. The chapters highlight the wide variety of actors involved in advocacy work, including NGOs, social movements, international institutions, governments, and businesses. Contributors use both qualitative and quantitative methodologies and bring to bear insights from political science, international relations, and sociology. The case studies also include diverse issue areas, from women’s rights to environmental protection, sustainable agriculture, health policy, and democracy promotion.
